Integral becomes null for a range of x values


I am attempting to compute a cumulative distribution function but there are chunks of the graph that reaches 0.

Thank you for your time,

Is it related to Continuous funtion plotted as discontinuous function ?

This is related to other numerical stability/rounding issues. We have a built-in way to plot CDFs that uses special techniques to avoid this kind of thing when we know we’re plotting a CDF instead of some arbitrary function. Here is the same graph, but much faster and more accurate: Untitled Graph.
